Descriptions
Mattermost fails to properly validate a RegExp built off the server URL path, allowing an attacker in control of an enrolled server to mount a Denial Of Service.
Mattermost no logra validar adecuadamente una expresión regular creada a partir de la ruta URL del servidor, lo que permite que un atacante con control de un servidor inscrito monte una Denegación de Servicio.
